A successful exploit could allow the attack... • http://www.securityfocus.com/bid/107311 • CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') CWE-264: Permissions, Privileges, and Access Controls •

CVE-2019-1593 – Cisco NX-OS Software Bash Shell Role-Based Access Control Bypass Privilege Escalation Vulnerability
https://notcve.org/view.php?id=CVE-2019-1593
06 Mar 2019 — A vulnerability in the Bash shell implementation for Cisco NX-OS Software could allow an authenticated, local attacker to escalate their privilege level by executing commands authorized to other user roles. The attacker must authenticate with valid user credentials. The vulnerability is due to the incorrect implementation of a Bash shell command that allows role-based access control (RBAC) to be bypassed. An attacker could exploit this vulnerability by authenticating to the device and entering a crafted com... • http://www.securityfocus.com/bid/107324 • CWE-264: Permissions, Privileges, and Access Controls •

CVE-2019-1594 – Cisco NX-OS Software 802.1X Extensible Authentication Protocol over LAN Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2019-1594
06 Mar 2019 — A vulnerability in the 802.1X implementation for Cisco NX-OS Software could allow an unauthenticated, adjacent attacker to cause a denial of service (DoS) condition on an affected device. The vulnerability is due to incomplete input validation of Extensible Authentication Protocol over LAN (EAPOL) frames. An attacker could exploit this vulnerability by sending a crafted EAPOL frame to an interface on the targeted device. A successful exploit could allow the attacker to cause the Layer 2 (L2) forwarding proc... • http://www.securityfocus.com/bid/107325 • CWE-20: Improper Input Validation CWE-264: Permissions, Privileges, and Access Controls •

CVE-2019-1588 – Cisco Nexus 9000 Series Fabric Switches Application-Centric Infrastructure Mode Arbitrary File Read Vulnerability
https://notcve.org/view.php?id=CVE-2019-1588
06 Mar 2019 — A vulnerability in the Cisco Nexus 9000 Series Fabric Switches running in Application-Centric Infrastructure (ACI) mode could allow an authenticated, local attacker to read arbitrary files on an affected device. The vulnerability is due to a lack of proper input and validation checking mechanisms of user-supplied input sent to an affected device. A successful exploit could allow the attacker unauthorized access to read arbitrary files on an affected device. This vulnerability has been fixed in version 14.0(... • http://www.securityfocus.com/bid/107316 • CWE-20: Improper Input Validation CWE-269: Improper Privilege Management •

CVE-2018-0395 – Cisco FXOS and NX-OS Software Link Layer Discovery Protocol Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2018-0395
17 Oct 2018 — A vulnerability in the Link Layer Discovery Protocol (LLDP) implementation for Cisco FXOS Software and Cisco NX-OS Software could allow an unauthenticated, adjacent attacker to cause a denial of service (DoS) condition when the device unexpectedly reloads. The vulnerability is due to improper input validation of certain type, length, value (TLV) fields of the LLDP frame header. An attacker could exploit this vulnerability by sending a crafted LLDP packet to an interface on the targeted device. A successful ... • http://www.securityfocus.com/bid/105674 • CWE-20: Improper Input Validation •
